Estimated stellar masses for SDSS and BOSS galaxies (Portsmouth method, passive model) Stellar masses using the method of Maraston et al. (2009). These fit passive stellar evolution models to the SDSS photometry, using the known redshifts. The model is a instantaneous burst stellar population whose age is fit for (with a minimum allowed age of 3 Gyrs). The population is 97% solar metallicity and 3% metal-poor, by mass. In this table we assume the Kroupa IMF.
